I'll challenge MSDNC........
No you won't, because you didn't post the entire story, which is exactly what we knew you would do. Pay attention to what she said in the beginning that was cropped out;
Well, today, the CDC reported new data that shows that under real world conditions, not just in a lab, not just extrapolating from tiny numbers of test subjects but looking at thousands of front line health workers and essential workers who have gotten vaccinated and who have since been doing their jobs and living in a real world, not only are the vaccines for those folks, thousands of them, keeping those people from getting sick from COVID themselves, those vaccines are also highly effective at preventing those people from getting infected, even with non-symptomatic infection. And if you are not infected, you can`t give it to anybody else.
And I know this sounds like an incremental piece of news, but sit on this for a second enough to absorb what this means, right? What this means is that we can get there with vaccines. We can end this thing.
It means that instead of a vaccine being able -- excuse me, it means instead of the virus being able to hop from person to person to person to person, spreading and spreading, sickening some of them but not all of them, and the ones it doesn`t sicken don`t know they have it and they give it to mere poem because they didn`t recognize, right? Instead of the virus being able to hop from person to person to person, potentially mutating and becoming more virulent and drug resistant along the way, now we know that the vaccines work well enough that the virus stops with every vaccinated person.
A vaccinated person gets exposed to the virus. The virus does not infect them. The virus cannot then use that person to go anywhere else. It cannot use a vaccinated person as a host to get more people.
A couple of important footnotes for these bubble head cultists to understand, is that the CDC reported new data. Not Rachel Maddow. And secondly, your video left out the part about these were health care workers the video was talking about, and that the vaccine was highly effective at preventing those people from getting infected. Which has been true. But your video cropped that out. So no, you aren't challenging anything.
Also, if you pay attention to her monologue, she left room for both scenarios. According to the data, Maddow mentioned you could get mildly sick or not infected at all. So what argument you think you are having with me, obviously does not exist. Lol!
